National Park Service wants to sharply raise entry fees at most popular parks

Visitors to popular parks, including Grand Canyon, Yosemite and Zion, could see fees double or triple to address backlog of maintenance and infrastructure costs

The National Park Service is considering a steep increase in entrance fees at 17 of its most popular parks, mostly in the American west, to address a backlog of maintenance and infrastructure projects.

Visitors to the Grand Canyon, Yosemite, Yellowstone, Zion and other national parks would be charged $70 per vehicle, up from the fee of $30 for a weekly pass. At other parks, the price hike is nearly triple, from $25 to $70.
